Same Day versus Staged Total Knee Arthroplasty: Do Cost Savings Justify the Risk?
Same-day bilateral total knee arthroplasties (BTKAs) are associated with increased complications compared with staged procedures; however, as complication rates and lengths of stay (LOS) for same-day procedures decrease, they may become attractive alternatives to staged procedures. The void of recent nationwide studies comparing the 30-day total cost and risks of these procedures inspired this propensity matched review. Therefore, we compared 30-day outcomes in staged and same-day BTKAs occurring in 2016 and 2017 using the National Readmission Database (NRD), a nationwide database. The NRD was queried for all same-day and staged BTKA patients from January 1 to November 30 for both 2016 and 2017. Since the NRD links readmissions within one calendar year, TKAs occurring in this month were excluded to allow 30-day follow-up. Propensity matching was performed based on demographics, producing 19,334 patients in both cohorts. Thirty-day readmission, revision, and mortality rates, hospital costs, LOS, discharge dispositions, and complications were analyzed. Chi-square and Student's
